Estou executando o Xubuntu 14.04 em um Dell Lattitude E7250 (placa de vídeo Intel) e tenho uma docking station Dell E-Port Plus. A docking station possui 2 portas DVI e 2 portas DP (DisplayPort) na parte traseira. Os monitores aceitam DVI ou DP, mas atualmente tenho apenas cabos DVI. Os dois monitores são monitores de 22 polegadas da Dell (modelo P2210).
Quando eu conecto o laptop e executo o xrandr, ele nem vê os monitores como conectados (nem a configuração gráfica do Display do Xubuntu). A saída xrandr é:
~ $ xrandr
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 32767 x 32767
eDP1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 277mm x 156mm
1366x768 60.0*+ 47.5
1360x768 59.8 60.0
1024x768 60.0
800x600 60.3 56.2
640x480 59.9
DP1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
DP2 disconnected (normal left inverted right x axis y axis)
HDMI2 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)
Como você pode ver, ele nem lista as saídas DVI. Se eu acionar o laptop desligado e ligá-lo, o X não iniciará nem mesmo.
Eu me preparei para escrever um xorg.conf que eu esperava que funcionasse com base em configurações anteriores como essa (mesmos monitores e dock, laptop mais antigo). Minha configuração preferida é que cada monitor tenha sua própria tela X, daí o uso de ZaphodHeads.
Usando esta configuração, o X não será iniciado. Aqui está o meu xorg.conf atual:
Section "ServerLayout"

Eu tentei isso com HDMI1 / 2, DP1 / 2 e DVI1 / 2 (mostrado aqui) como saídas.

Eu tentei inicializar com a tampa do laptop fechada ou sem. Quando vou a um terminal virtual, os dois monitores externos acendem e espelham a tela do laptop. Mas não X de jeito nenhum, não como. Alguma ideia? Vou pegar alguns cabos de DP amanhã para ver se isso funciona. Mas esta mesma configuração funciona no Windows 7, por isso eu detesto lançar mais hardware no problema.
